Chapter 465 The first bottleneck of heavy industry
It was the end of February 1790 when Zhang Bingwen came out of Beihai Town Central Hospital after a hundred days of broken bones.
Although this hospitalization caused Zhang Bingwen's family to miss the opportunity to be assigned to work as farmers in Boli Town, because he had worked in a blacksmith shop for two years in his hometown, he was assigned to the ironmaking workshop of the Beihai Town Steel Plant after being discharged from the hospital.
, as a sampler.
Sampling workers, like thermometer workers, are the two basic types of work in iron and steelmaking workshops. They are actually just odd jobs. This is the most unskilled type of work, the most physically tiring, and also the lowest paid. In addition to having to work frequently
I have to run errands, send samples for quality inspection, and do other chores.
In fact, in front of the furnace, everyone has to start from the most basic temperature measurement and sampling; those who do well will be promoted, up to the position of furnace director, no one can take key positions right away.
However, for Zhang Bingwen, this was nothing less than joy falling from the sky. The sampler's salary was 10 Beihai dollars per month, which was equivalent to two taels of silver, and he could buy 200 kilograms of white flour at a Beihai trading company.
A family of three must be well off with two hundred kilograms of white flour, and the steel factory also provides two meals a day, which are large and sufficient, and they also provide work clothes. But Zhang Bingwen's family has four people, and the fifth one is about to welcome them.
Fortunately, both of Zhang Bingwen's children went to primary school in Beihai Town to read and study, and the school provided one lunch every day; his wife, Zhang Huang, also got a job collecting shoe soles from the residents' mutual aid group. Each pair of shoe soles cost 2 cents to make.
Huang makes a pair in three days and earns 2 Bei Hai Yuan a month.
In fact, this is a temporary rescue job. When Zhang Huang is able to work in the fields after giving birth, she may be assigned to work in a shoe factory. Currently, the shoe factory in Beihai Town has already used
The hand-operated thick-thread sewing machine can make soles many times faster than hand sewing.
Even so, Zhang Huang calculated her income of 12 silver dollars and felt that she was already living a life like heaven.
Her husband didn't spend a penny for hospitalization, and the doctor at the hospital also examined Zhang Huang and told her that the fetal position was straight and everything was fine.
The house was issued by the civil administration and is free to live in. Although the area is not large compared to other old immigrant families in Beihai Town, with only two east and west rooms and a small entrance hall, for Zhang Huang, it is already better than the adobe house in his hometown.
It’s dozens of times higher.
The blue cotton-padded jacket she was wearing was also issued to her by the immigration department. Not only she, but also the whole family had one set, including shoes.
In fact, the immigration department in Beihai Town is quite helpless. The people who come here are all refugees, and they are originally dressed in ragged clothes. This is okay in summer, but in winter it is dozens of degrees below zero. If you don't wear clothes, you will freeze to death.
Furthermore, unlike other resettlement sites, there have long been no cellars here in Beihai Town, so anyone with skills who can stay here will be treated better than other refugees.
The only thing that made her feel a little regretful was that Beihai Trading Company only sold white flour and rice, and the sorghum rice she used to eat was not available at all. Although white flour was delicious and cheap, ordinary landlord families in Guanhai did not dare to eat like this!
The couple was so excited that they didn't close their eyes for half the night, lying on the bed chattering about the beautiful life in the future.
"Dad, do your arms and legs still hurt?"
"It doesn't hurt anymore. I think I can earn two taels of silver a month and nothing will hurt anymore."
"Dad, my life is really like a dream."
"But no, if I had known that I would have such a day, I wouldn't have gone to Chibaoju."
"Then do you regret it?"
"I won't regret it if I can make sure you three have enough to eat."
"You have such a stubborn temper, like a cow. You have to hit the south wall, and you always get a bloody head. If you hadn't offended the county guards, you wouldn't have lost your job at the iron factory."
"I just can't stand how domineering they are! My father was right. He said, what the hell, it's not a disaster to lose a horse."
"Is it a horse, not a commodity? What kind of commodity is it not?"
"Just saying that losing a horse is not necessarily a disaster. Maybe there will be good things later."
"What my father-in-law said is quite reasonable. It's a pity that his old man and mother were gone when I came through the door, and he didn't drink the tea I offered him."
"My father used to say that he traveled all over the world just to serve a bowl!" Zhang Bingwen suddenly felt a sore nose and tears began to well up in his eyes.
The woman hurriedly came over to coax her a few words, then changed the subject, talking about how she had to get paid tomorrow to pull pieces of cloth to make clothes for her daughter Yaya and her son Huzi, and she also had to prepare clothes for the child who was about to be born...
..
Zhang Bingwen's father actually said that a blessing in disguise may lead to disaster later.
Sure enough, on the morning of the next day, Zhang Bingwen took the note from the Immigration Department and went to the Public Security Police Station to apply for a work permit, and a photo incident ensued.
To apply for a work permit, you must take a photo. After seeing the three-inch photo of himself, Zhang Bingwen was so frightened that he cried out and begged the security policeman who took the photo to return his soul to him.
The security police have seen too many ridiculous things like this, and it was the same when they first came to Beihai Town. However, he used another set of words for Zhang Bingwen.
"Remember! You are not allowed to leave your badge when working!"
"Yes. Master, what about when I go home and sleep?"
"Keep it close by. Note, if you lose it, you will be fined ten yuan."
When Zhang Bingwen heard this, he thought to himself, "Oh my god, we only earn ten silver dollars a month, and this card is worth two taels of silver. There is really no way to reason." Then he asked unwillingly: "Master, what's wrong with that?"
What should I do?”
"This is sealed. No water or dirt can penetrate it. Do you understand?"
"Yes. I understand."
It is said that people who work on the east bank of the Xila River must first go to the Public Security Police Station to get a work badge and enter their fingerprints, otherwise they will not be able to enter the factory gate. If they are here to spy on secrets, even if they sneak into the factory in Beihai Town, they will have to
It will be difficult to escape again.
The security police had arrested two guys before, and the two men seemed frightened that they could be caught so quickly. They couldn't figure out how they were discovered.

Multiple base stations on the coast can be tracked through triangulation.
When the communication chip is connected to the base station signal, the monitoring personnel can determine the location of the person based on the signal strength of the person and the three surrounding base stations. This calculation method is called the "triangulation calculation method."
Although this method has errors, the distance of a few meters is still acceptable. Through this method, Beihai Town effectively prevented all parties from spying. Those spies never imagined that as long as they entered the east bank of the Xila River, they would already be in Beihai Town.
Under the surveillance of "Eye of the Sky".
By the way, of the two people who spied on the secrets of the factory, one was a spy sent by the shogunate and the other was from the Manchu.
At present, the only one who can enter and exit the training base without taking pictures is Wu Zhong. This is a special case. Wang Yuanfang rushed to ask for help, but he still asked the other party not to lose his identity tag.
After Zhang Bingwen reported to the ironworks, because his newly healed arm was still not feeling well, the furnace director temporarily asked him to be responsible for sending samples back and forth.
This morning, as soon as he returned from delivering things to the quality inspection department, he saw seven or eight people in uniforms coming from the factory, surrounded by a tall young man. He stood at the door of the workshop for a while, and then walked around to
Went behind.
What surprised Zhang Bingwen was that everyone in the workshop who had nothing to do would bow to the man's back from a distance. So he asked one person: "Who is that? Why are you rushing to him?"
bow?"
"You actually don't know who he is?!" The worker shook his head in confusion when he saw Zhang Bingwen, so he explained: "That's Prince Zhao! You are wearing the clothes given by him and living in the house given by him.
Don’t you know his old man?”
When Zhang Bingwen heard this, he quickly ran to the door, bowed in the direction of the backyard, and then said with some embarrassment: "I, I have been in the hospital before, and I have never seen him before."
Zhao Xin didn't know that he had become an "old man". He came here today to see Zhao Liang.
Beginning in March this year, Beihai Town will begin to imitate later Springfield Model 1863 rifles.
This front-loading smoothbore flash cap gun provided to the servant army is named "Model 1790 Rifle". It uses paper tubes to load ammunition, and the flash cap is fired. The rate of fire can reach 2 to 4 rounds per minute. The muzzle velocity is 300 meters.
to 430 meters per second, the effective range is 180 to 370 meters, and the maximum range is 730 to 910 meters.
The new muzzle-loading rifle is not sold to the outside world. It is only equipped to the island countries in the Northern Navy sequence and the Ainu servant army. Since you want people to help you fight the war, especially against Tsarist Russia, you can't always use revolvers, no matter what the rifle is.
It also needs to be equipped.
Before starting production, Zhao Liang, the boss in charge of the "military-industrial complex", decided to hold a two-person meeting, mainly to discuss with Zhao Xin what kind of steel materials and specifications to use in order to determine the manufacturing cost and external sales price.
However, Zhao Liang did not talk about guns at first, but talked about the upcoming group of new people, that is, professionals in steel and steel rolling.
At present, the development of heavy industry in Beihai Town has reached a bottleneck point. Zhao Liang's level of steel refining and metal machining alone is far from meeting the requirements of heavy industry development.
For example, large gears used for locomotive traction, supercharger transmission gears, rear axles, extremely loaded connecting rods and spring clips, bending machine molds, oil deep well drill pipe joints and seamless steel pipes, etc., all need to be used.
AISI4140 alloy steel.
The development of this kind of extremely high-strength alloy steel is also very difficult, mainly because the quality of the blank, the dimensional accuracy of the rolled material and the heat treatment process are very high, which is simply not what Zhao Liang can do.
Another example is high manganese steel, which can only be produced in small batches now, and the Northern Navy will need more cannons that can fire farther in the future.
There is also the silicon steel used to make the motor rotor core, and the No. 45 steel currently needed to imitate the M1863 rifle.
So this year, Zhao Xin took advantage of the Spring Festival to send people back, and asked his cousin's company to start recruiting professionals in steel and steel rolling all over the country. With Wu An'an's lesson, Zhao Xin only wanted people over fifty years old this time.
At least a hundred.
The main tasks of these people after arriving are to formulate the steel composition, process route, and organize the process parameters during the production process. This is something that only professionals can do. Furthermore, they need to bring out a large number of apprentices.
The location of the new steel plant currently selected by Zhao Xin is located in Boli Town, which is on the west bank of the Huntong River. Starting from mid-March, the construction team under the Civil Affairs Bureau will enter the site and start leveling the land in the planned area.
After chatting about recruiting, Zhao Liang got down to the topic: "For the barrel of the 1790 rifle, I plan to use a No. 45 seamless steel pipe with an outer diameter of 22, an inner diameter of 16, and a wall thickness of 3 mm. To be honest, it is expensive.
Yes, but the material performance is definitely no problem.”
Zhao Xin nodded, found a piece of paper and wrote down the data on it, and asked casually: "Does that mean the caliber is 16 mm? I said, brown basses have 19 mm, and the French also use 17 mm. Is ours too small?
Already?"
"It's not small. M1863 is only 14.732 mm. Besides, the performance of our black powder is much better than what the Europeans are using now."
"Okay, you continue."
"The dimensions of other parts of the gun body remain the same as the M1863, and the barrel length is 1,400 mm."
Zhao Xin asked while writing down: "How much does it weigh?"
"A lot lighter than the original gun." Zhao Liang rattled off the specifications of the imitation weapon: "The weight of the seamless steel pipe per meter is 1.40562 kilograms, 1400 mm is 1.968 kilograms, plus the locking bolt 0.08 kilograms, the bolt combination is 0.3
Kilogram, if the wooden stock is 1.5 kilograms, the total weight is 3.847 kilograms, and the original gun is 4.1 kilograms."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Well, it's okay. I mainly consider whether the small bodies of the islanders can carry it, otherwise when the time comes, they will be smashed if they can't carry it.
It’s in.”
"By the way, I went back and asked about the seamless steel pipe we need this time. The length is five meters, and the market price per ton is around 62,000, excluding shipping costs."
So Zhao Xin calculated based on these data. If one barrel is 5 meters long, each barrel can be used to make three barrels. Five thousand barrels is 35.14 tons, which is about 2.18 million.
If you don't consider shipping costs and only include processing and other materials, the average cost of each rifle is less than 200 yuan, which is less than the price of one gram of gold.
As long as the planned "Cossack Kingdom" can gain a foothold in the West Siberian Plain west of the Yenisey River, then both the Lena River and the gold mines north of Irkutsk will be in its pocket. And once the Tsarist Empire
Being cut off from the eastward route, wouldn't it be easy to take over Alaska as our own... Hey, there are so many unclaimed lands these days.
Thinking of this, Zhao Xin suddenly felt a lot happier. He stood up and said, "I'll leave if it's okay?"
"Of course not." Zhao Liang threw aside the materials in his hand and continued: "The inventory of SKS barrels is not enough. The early batches of ammunition we made did not have good primer technology and were too corrosive to the barrels.
You have to buy at least 20,000 more guns, and the barrels of the first batch of guns have to be replaced."
Zhao Xin nodded and said, "Okay, I understand."
The so-called barrel life refers to the number of bullets that can be fired by the barrel while ensuring accuracy. Taking SKS as an example, if the shooting accuracy is not considered and there is no high-density continuous shooting, you can shoot 20,000 or 50,000 rounds at will.
hair.
Because the rifle in the barrel will cause the caliber to be slightly smaller, and the diameter of the bullet is slightly larger than the diameter of the barrel plus the rifle. When shooting, the warhead is squeezed into the barrel by the gunpowder gas under the pressure of the gunpowder explosion.
When the bullet hits the rifle line and is forced to rotate, the warhead will wear the rifle line to a certain extent. When the rifle line is worn to a certain extent, the diameter of the barrel becomes larger and the accuracy naturally decreases.
In addition, the friction between the gunpowder gas and the warhead and the rifle wire will cause the entire barrel to heat up, the metal will expand when heated, and the diameter of the barrel will naturally become larger, resulting in a decrease in accuracy.
Theoretically, as long as a standard-diameter bullet cannot be inserted into the mouth of the barrel, the barrel can still be used. For barrels that pursue precision, such as HK416, the requirements are much higher. Generally, it is average
When the moa number exceeds 50% to 150% of the optimal moa value, the barrel should be replaced with a new one.
In fact, the life of the gun barrel depends on many factors, such as the frequency of shooting. When the barrel is hot, do you have to wait until it cools down before shooting? Has the new gun been run-in? Is maintenance in place in time? Are corrosive bullets with acid primers used?
Does the explosive contain corrosive substances? You must know that the destructive effect of acid corrosive gunpowder on the barrel is equivalent to no chrome plating.
Another key point is the rifling grinding tools. In another time and space, the arsenal usually replaces a set of grinding tools for every thousand barrels produced. For example, A's barrel is the first to be produced, and B's is.
Nine hundredth, then the barrel life of person B must be not as good as that of person A.
When it comes to industry, especially military industry, nothing should be careless. If basic industries are not developed, materials and technology are not up to standard, there will be a lot of trouble.
